MACHINE FOR. FINISHING TUMBLERS 03 OTHER narrows.

To all whom it may concern:

Beit known that I, ALBERT B. KNIGHT, a citizen of the United States, residing at Fairmont, in the county of Marion and State ofVVest Virginia, have invented certain new and useful Improvements in Machines-for Finishing Tumblers or other Articles, of

- which the following is a s ecification.

The subject matter 0 this invention is shown but not claimed in my co-pending application for Letters Patent, Serial No. 591,624, filed November 10, 1910, of which the present application is a division.

An important object of thls inventlon 1s to provide means to melt the upper end of the tumbler after the same has beencracked off, such means being readily adjustable so that the same may be employed in connection with articles of different sizes.

'A further object of this invention is to provide means to smooth off or shape the heated end of the tumbler, such means being so constructed that it does not prevent the game from coming in contact with the tumler.

Other objects and advanta es ofthis invention will be apparent during thecourse of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side view of my combined machine for cracking off and finishing tumblers, Fig. 2 is a central vertical sectional view through the means for supporting and rotating the tumbler and through a hurner structure for heating the same, Fig. 3 is a side elevation of an adjustable support for the burner structure, Fig.4 is abottom plan view of a device for smoothing oil or shaping the upper end of the tumbler, and Fig. 5 is a verticalsectional view taken online 5-5 of Fig. 4.

Patented Nov. 21,1911. ivided and this application filed the lower portions of the legs 2 and 3. Suitably mounted upon the support 4 near one end of the machine, is a motor 5 of any well known or preferred type. This motor has its armature shaft 6 provided outwardly of the legs 2 with a small pinion 7, having ongagement with a large plnion 8. The lnion '8 is rigidly mounted upon a horizontal actuating shaft 9, disposed below the support 4 and suitalrly journaled through bearings 10. Rigidlymounted upon; the support 4 near its center, is a vacuum pump 11 of any well known or preferredtype, which is operated by a crank-shaft 12 carrylng a sprocket wheel 13. This sprocketwheel is rotated by a sprocket chain 14 operating through suitable openings formed in the support 4 and engaging a sprocket wheel 15 carried by the actuating shaft 9. Rigidly mounted 11, 1s a vacuum tank 16, which is connected with the pump by a pipe 17. Disposed near and below the top 1 is a rotatable line-shaft 18, which is journaled through "stationary bearings 19. This line shaftisprovided in- '70 upon the support 4 to one side of the pump tel-mediate its ends with a step pulley 20,

about which is trained a belt 21, extending,

downwardly to operate through openings (not shown) formed in the support 4. This belt is trained about a step pulley 22 rigidly,

connected with the inner end of the shaft 9. From the description of the above'referred to parts, it is obvious that the rotation of the armature shaft- 6 is imparted to the actuating shaft 9, which is connected up to drive the pump 11 and the line shaft 18.

Suitably mounted at one end of the top 1 are means for cracking off the tumbler, such means comprising broadly a rotatable spindle 23 carrying a plate 24 upon its upper end. The spindle receives its rotation from a worm-wheel having engagement with a worm 26 formed upon the line shaft 18. V The spindle 23 is tubular and is connected with a valve structure 27 by a pipe 28. This valve structure is connected with the tank, 16 by a pipe 29. By proper manipulation of the valve vertical support 30 which is suitably mounted upon the top 1. This support adjustably holds a burner 31, which is adapted to providea ame to heatthe tumbler in a zone in which the same is being scored, by means to be described. An upright 32 has suitable connection with the top 1 and supports a scoring device 33. This scoring device includes a reciprocatory diamond pointed needle 34 which is adapted to move into and out of engagement with the tum bler. Means are provided to effect the movement of the needle, to which is connected a pipe 35, having suitable connection with the valve structureli'. When the valve structure is moved in one direction a vacumn is first created below the tumbler for holding the same and then a vacuum is created in the pipe 35 to operate the means which move the needle 31. This cracking otl' apparatus is shown and described in detail in my pending application Serial No. 591.624, filed November it 1910. .\s the -cracking otl' apparatus will not be claimed in the present application no further description thereof is deemed necessary.

The present. application relates more particularly to means for heating the upper end of the tumbler after the same has been cracked ofl'. Such means comprises a rota- .table support for holding tumbler and a burner structure for providing a flame to heat the tumbler. In Fig. l. l have shown two rotatable supports 36 and it is to be understood that my machine may be equipped with any number of such supports as IS found practical in the construction and opcrition of the same. Each of these rotatable supports, as shown in Fig. 2, comprises a vertical cylindrical casing 37, which is disposed within an opening formed through the top 1. The casing 37 is provided midway its ends with an annular flange 38, which is bolted to the top 1, as shown at 39. \Vithin the casing 37 is rotatably mounted a spindle 40, provided near its upper end wit-h an annular flange 41, fitting within a counter-bore 42. The flange 41 prevents the downward displacement of the spindle. The spindle has a worm-wheelt43 rigidly connected with its lower end and operating in engagementwith the casing 37. The upper end portion of the s indle 40 is provided with a preferably circu ar guard 44, to prevent material from dropping between the spindle 40 and the casing 37. The spindle 40 is provided with an axial opening formed therethrough, for receiving a shatt 45, which is held against rotation in said spindle by clamping screws 4c. The shaft 45 may be keyed to the spindle if desired." The upper end of the shaft 45 is screwthreaded for engagement with a boss 47, which is formed to 48. This plate is provided upon its upon the lower side of a circular horizontal p a upper side and centrally thereof wit-h an upstanding boss 49, as shown. Removably mounted upon the plate 48 is a holding-ring 50, provided with a recess 51 for receiving the lower end ofthe tumbler 52. The bottom wall of the recess is provided with an annular groove, for receiving packing 53.

Disposed above each of the rotatable supports is a burner structure 54, which is adapted to provide a flame, which may be circular or other shape, corresponding to the shape of the upper end of the tumbler 52 or other article. The burner structure comprises a tubular body portion which is detachably mounted within one end of a supporting bracket 56. A clamping screw 57 holds the tubular body portion against displacement. The opposite end of the bracket '56 is vertically adjustably mounted upon a shaft 58, which shaft is in turn adjustably mounted upon the top 1. The lower end of the verticallydisposed shaft 58 is disposed within a sleeve 5!) and held therein v clamps the head til to the top 1. A. claniping screw. 65 is provided to hold the bracket 56 in adjustment at difl'erent posit-ions upon the shaft 58. The tube 55 has its lower end sermv-threaded, as shown at 66, for engagement with a deflector (57, which has the lmvcr portion thereof formed substantially frusto-conical and increases in diameter downwardly. At a. point near and spaced from thescrew-threads 66, the tube is provided with a screw-threaded portion'68. Arranged above the deflector 67 is an approximately three-fourths spherical casing 69, having its lower end provided with a preferably circular opening 70, for receiving the deflector (S7. A tubular sleeve 71 is formed upon the upper portion of the easing 69 and is internally screw-threaded for engagement with the screw-threaded portion (38. A clamping-ring 7 2 engages the screwthreaded portion 68, and prevents accidental rotation of the casing 69. By proper rota- .;tion of the casing 69, .said casing maybe changed accoruing to the circumference of the article to be heated. The tube is pro-- vided within the casing (39 with a plurality of perforations 73, for the passage. of carbureted fuel into said casing 69. The tube 55 is provided at its upper end with.screwthreads 74, for engagement with a T-coupling 75. A gas supply pipe 75 is connected .with this coupling-for supplying gas within the tube 55. An air supply pipe 76 is also connected with the coupling 75, to conduct air into the tube 55 for carbureting the gas.

In Figs. 2, 4 and 5, I have shown a device for smoothing oil the upper end of the tumbler'52 while the same is being heated. This device comprises a preferably circular head 77, to which is secured a handle 78. The head 77 is provided with spaced segmental openings 79 formed therethrough, which are connected by grooves 80 formed upon the lower surface of the head 77. The grooves 80 are segmental and form, in effect, a circle. These grooves are adapted to receive the up er end of the tumbler. \Vhen the head 7 is placed on the tumbler 52 so that the upper end of the tumbler fits in the grooves 80, (the upper end of the tumbler being previously heated to the melting point, and the tumbler being rotated,) when the operator presses gently on the head 77, the heated end of the tumbler will be deprived of all irregularities caused by the cracking ofi of thesa'me. The upper end of the tumbler is still being heated when the head 7 7 is applied thereto, as the flame can pass through the segmental openings 79. The line shaft 18 is provided with worms 81, which engage the worm-wheels 43.

In the operation of the machine, after the tumbler has been cracked ofl, the same is placed in the'holding-ring '50 and is slowly rotated thereby. The burner structure is then brought in a suitable position and the casing 69 adjusted'so that'a flame of the proper size is provided. to engage the upper end of the tumbler. lVhen the u per, end of the tumbler is heated to the me ting point, the head 77 of the smoothing device is placed upon the revolving tumbler so that the upper end of the same will fit within theslots '80, it being understood that vthis smoothing device may be held stationary by the operator or oscillated by him. The smoothing device does not prevent the flame engaging the upper end of the tumbler,

said flame passing through the segmental openings 79.

. I wish it understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that certain changes in the shape, size and arrangement of parts ma be resorted to without departing from t e spirit of my invention or the scope'of the subjoined claims.
